NASA’s plans to return to the moon and launch an Apollo-style mission to Mars have been hampered by the fact that they simply don’t have enough money, raising the question of whether we should let financial constraints restrain human vision.

The Human Space Flight Plans Committee, formed by President Obama, stated in their report that without a significant boost in NASA’s current budget, not only will it be impossible to return to the moon by the goal of 2020, but astronauts might not be able to go at all.
